They appear to honk when a car is backing up within X feet towards them.
Yup. And the issue here is that the cars back into and out of the parking spots, and are also programmed to stop if they get honked at. So car 1 begins backing into a spot, car 2 honks, car 1 pauses and then begins backing again, car 2 honks again, repeat… And when you have 30 cars in a parking lot, all trying to find a parking spot, there’s a lot of backing up and a lot of honking.
